The Eppendorf 5427R Refrigerated Centrifuge 5427R has an aerosol-tight 48-place rotor increases productivity and can handle though challenges in a safe and reliable manner at a maximum speed of 25,000 x g. The rotors are equipped with the Eppendorf Quick Lock lids for ease of opening and closing the rotor lid requiring only a quart turn. Plus, for operational safety there is automatic rotor recognition and imbalance detection. The lid will lock automatically with a soft-touch, one-finger ergonomic approach. This centrifuge has temperature range of -11 °C to 40 °C and a FastTemp feature that allows for quick pre-cooling. A condensation drain is built-in to eliminate water accumulation. You can program the ECO shut-off to engage after 1, 2, 4, or 8 hours of non-use.

Centrifuge Inspection and Recertification Checklist

• Confirm the power supply output voltages match specified requirements for stable distribution to all internal components
• Measure and verify voltages at PCB test points to ensure accurate power delivery and circuit integrity
• Confirm rotor compatibility with the centrifuge model and check that rotor detection systems recognize the rotor type
• Inspect the exterior for any cosmetic or structural damage that could affect performance or safety
• Check the door mechanism alignment to ensure secure and smooth opening and closing
• Inspect and replace the gas strut with an OEM part to maintain proper door support and safety
• Examine the rotor chamber bowl for dents or damage and replace as needed to ensure safe operation
• Replace and confirm full functionality of all lid lock switches to maintain secure closure
• Inspect and lubricate the door lock mechanism, applying grease to the lid lock rail for smooth operation
• Test compressor functionality (if applicable) to ensure proper operation and consistent temperature control
• Conduct an 8-12 hour cycle test to validate consistent performance over prolonged use
• Confirm rotor motor stability, check for unusual noise, and assess mechanical integrity during operation
• Inspect the condensation drain and clear any clogs to prevent moisture buildup in the rotor chamber
• Verify RPM accuracy using an NIST-traceable tachometer and perform calibration as necessary
• Check the centrifuge error log to ensure zero recorded issues, confirming system reliability
